This document discusses broiler nutrition management. It covers basic nutritional components including water, amino acids, energy, vitamins and minerals. It discusses factors that affect nutrient content in feed such as ingredient quality and feed form. It also discusses key factors in selecting optimal diets such as raw material costs and market requirements. The document outlines different feed forms and the benefits of pelleted feed. It provides details on protein, energy, and micronutrient requirements. It discusses phase feeding programs and different diet types based on production objectives. Feed testing and withdrawal are also covered. The document concludes with notes on supplementing whole wheat feeding for broilers.

1. 9. NUTRITION MANAGEMENT
Broiler Management Guide

2. Introduction
• Broiler diets
▫ Energy
▫ Nutrients
• Health and Efficient production

3. Introduction
• Basic Nutritional Components
▫ Water
▫ Amino acids
▫ Energy
▫ Vitamins
▫ Minerals
• To assure correct
▫ Skeletal growth
▫ Muscle disposition

4. Introduction
• Factors affecting Nutrient content of the
feed
▫ Ingredient quality
▫ Feed form
▫ Feed hygiene
• If compromised
▫ Performance can be decrease

5. Introduction
• Key Factors in selection of optimum diets
▫ Raw material availability and cost
▫ Separate sex growing
▫ Live weights required by market
▫ The value of meat and carcass yield
▫ Fat levels required by specific market
▫ Skin color
▫ Meat texture and flavor
▫ Feed mill capabilities

6. Introduction
• Feed forms
▫ Mash
▫ Crumble
▫ Pelleted
▫ Extruded
• Further processing is often preferable
▫ Improved in flock efficiency

7. Crude Protein
• Requirements for amino acids
▫ Building blocks of protein
• Proteins
▫ Structural components in tissues
▫ Feathers to muscle

8. Energy
• Necessary for maintaining the bird’s basic
metabolic functions and body weight
growth
• Metabolizable energy (ME)
▫ Energy content of poultry diets
▫ Gross amt of energy of a feed consemed
minus the gross amount of energy excreted

9. Micronutrients
• Vitamins
▫ Routinely supplemented
▫ Water soluble
 B-complex vitamins
▫ Fat soluble
 A, D, E and K
 Can be stored in liver and other parts

10. Micronutrients
• Minerals
▫ Inorganic
▫ Major elements
 Ca, P, K, Na, Cl, S, Mg
▫ Trace elements
 Fe, I, Cu, Mn, Zn, Se

11. Feed testing
• Feed sampling
▫ Systematic approach
▫ ‘’best practice’’ policy
• The analysis reflects the real nutrient
content of feed
▫ If good sampling technique was done
• Take sub-samples (eg 5)
▫ Combine into a composite sample
▫ 5 samples per each delivery of feed taken

12. Feed testing
• Sampling from feed lines
▫ Not recommended
▫ Sifting of ingredients or feed will skew results
• Samples should be stored in a refrigerator
▫ Recoded with date, feed type and delivery
ticket number
• If problem arises, feeds should be analyzed
▫ Reports should be compared with nutrient
specifications for the respective diets

13. Phase feeding
• Nutrient requirement
▫ Decline with broiler age
• Starter, Grower and Finisher diets
▫ Incorporated into the growing program of
broilers
• Changes in nutrients should not be done
abruptly on specific dates but rather
continuously overtime

14. Phase feeding
• The greater the number of feeds a bird
receives, the closer to feed the birds to
the requirement.
• The number of feeds is limited by these
factors
▫ Economic
 Transportation cost
 Farm capacity
▫ Logistical
 Feed mill capacity

15. Phase feeding
• Dietary concentrations are based on the
objectives of the producer.
• There are three (3) objectives of feeding
broilers
▫ Most producers use a combination of these

16. Diet Type 1
• Nutrient-rich
▫ To optimize live weight gain and feed
conversion
• Promotes additional carcass lipid content
• Also, metabolic disorders
• Diet cost will be high

17. Diet Type 2
• Lowered energy content
• Optimum crude protein and amino acid
content
• Results into less lipid gain but maximize
lean mass production
• Live weight and feed conversion
▫ Will be negatively affected
• Cost per lean mass will be optimal

18. Diet Type 3
• Low nutrient concentration
• Result in lower live weight growth
• Higher feed conversion
• Cost per live weight may be optimum

19. Feed withdrawal
• Special attention towards medication and
vaccine withdrawal dates
▫ To ensure no residue retained in carcass at
processing
• Always keep records.

20. Supplement Whole Wheat feeding
• Whole wheat to broiler chickens?
▫ Being practiced around the world
▫ Reduction in feed cost
▫ Improvements in gizzard development
 Improved digestion
 Ability to manipulate the nutrient intake

21. Supplement Whole Wheat feeding
• Disadvantages?
▫ Reduced growth rate
▫ Reduction in lean gain
▫ Poorer uniformity
 If adjustments in compound feed are not
made

22. Supplement Whole Wheat feeding
• Maybe added either in
▫ feed mill-
▫ farm- preferably due to flexibility if offers
• Around day 7 or when birds weigh 160 g
▫ Begin supplementing
▫ Level of 1%-5%
▫ Inc to approx. 30%, gradual inc by 1-5%

23. Supplement Whole Wheat feeding
• The maximum percent (30%) depends on
▫ Compound feed quality
▫ Nutrient density
▫ Wheat quality
▫ Desired performance
▫ Performance of individual flocks

24. Supplement Whole Wheat feeding
• Important reminders!!
▫ Supplementation leads to dilution effect to
the diet.. Make adjustments!
▫ Medications need to be adjusted
▫ Regular monitoring of bird live weight
 To see the effects to the flock
▫ Supplemental whole wheat should be
removed 48 hours before slaughter
 To avoid contamination of carcass during
eviceration
